Quality check 07, Block group intersections with neighborhoods
Satya Golla, Mounika Jakkidi, and Steve Simon
Created 2022-03-21
This program examines block groups that only partially intersect with community districts.
In the cd.RData file, Rosedale has cd_id=209, Swope Park has cd_id=110.
Interesting neighborhoods might be Terrace Lake Gardens, Colonial Square, Hidden Valley, Crossgates because each of these coincides with a single tract.
Ruskin Heights Eastwood Hills East have four tracts totally inside. Bannister Acres has two tracts totally inside.
Swope Parkway-Elmwood has three tracts, one totally inside and two partially inside. Vineyard is also similar. Glenhaven, East Swope Highlands has two tracts, one totally inside and one mostly outside.

# bg = block group
